The quest was very interesting! We went through it with kids aged from 8 years. We gave them paints and sparking gel to decorate their masks. The masks were fastened on their ears with a complicated system of rubber bands.
For older kids, we arranged a workshop on scary makeup (to scare off the ghosts), drawing bloody wounds on their hands and faces. The Internet is full of information of this kind. Teenagers loved it! The walls and ceiling were decorated with spider webs and ghosts made of bandages hanging from balloons.
For the stage with the ice hand, we took that hand out at the last minute and put it into a jar from Ikea filled with cold water. That’s surprising but it didn’t catch the eye.
